| Volume | The amount of space an object takes up |
| Cohesion | The force of attraction between two molecules of the same kind |
| Mass | The amount of matter in an object |
| Solid | The state in which matter has definite volume and shape |
| Crystalline Solid | A solid whose particles are arranged in a regular and repeating 3-D pattern |
| Density | The mass per unit of volume of a substance |
| Liquid | The state in which matter has a definite volume but not a definite shape |
| Gravity | A force that pulls two objects together because of their masses |
| Matter | Anything that has mass and takes up space |
| Phase | A state or different form in which matter can exist |
| Viscosity | A liquid’s resistance to flow |
| Kinetic energy | energy in motion or moving objects |
| Boyle’s law | Volume decreases as pressure increase |
| Charles’ law | volume increases as temperature increases |
| oxidation | when metal is chemically combined with water vapor an/or oxygen forming rust |
